Description

Technical Field

[0001] The utility model relates to the technical field of bearing processing equipment, in particular to a bearing part surface processing device. Background Art

[0002] Bearings are an important component in contemporary mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. According to the different friction properties of the moving elements, bearings can be divided into two categories: rolling bearings and sliding bearings. During the machining process, after the bearings are machined, the surface roughness of the bearings may not meet the standard, affecting their service life. Usually, the surface of the bearings is polished manually, which greatly reduces the progress of the polishing work. In the prior art, most bearings are fixed by bidirectional clamping, and there is a lack of limit fixing for bearings of different specifications. There is no limit clamping for the bearings in multiple directions, and it is impossible to fix them from the inside of the bearings, and only the surface of the bearings can be clamped.

[0028] A fixing mechanism 5 for bearing positioning arranged on the top of the table 1;

[0029] The fixing mechanism 5 includes a ring body 51 fixedly installed on the top of the table top 1 by four rods, three grooves 52 are opened inside the ring body 51, springs 53 are clamped inside the three grooves 52, and sliding seats 54 are clamped at adjacent ends of the three springs 53. The tops of the three sliding seats 54 are integrally machined with resistance blocks 55, and the bottom of the ring body 51 is provided with a pushing member 50 for synchronously driving the three sliding seats 54.

[0030] The pusher 50 includes two electric push rods 501 fixedly mounted on the bottom of the ring body 51, a pull plate 502 fixedly mounted on the bottom of the two electric push rods 501, a sphere 503 fixedly mounted on the top of the pull plate 502, and the bottoms of the three sliding seats 54 are all arranged in an inclined plane, and the inclined planes of the bottoms of the three sliding seats 54 are all in contact with the surface of the sphere 503;

[0031] In this embodiment, the bearing parts to be processed are placed on the top of the ring body 51, and the two electric push rods 501 are started. At the same time, the two electric push rods 501 are synchronous push rods, which drive the pull plate 502 to move upward, so that the sphere 503 on the top of the pull plate 502 squeezes the three sliding seats 54, forcing the three sliding seats 54 to slide in the groove body 52 and move away from each other, wherein the axis of the sphere 503 and the axis of the ring body 51 are on the same vertical line, and the abutment blocks 55 on the top of the three sliding seats 54 abut from the inner ring of the bearing to fix bearings of different specifications, and the two cylinders 2 are started. The two cylinders 2 are synchronous cylinders 2, which drive the lifting plate 4 to move downward, and the grinder 3 inside the lifting plate 4 is started to grind the bearing surface fixed on the top of the ring body 51.

[0033] Specifically, during the movement of the sliding seat 54 , the sliding rod 6 is driven to slide in the circular hole 7 inside the ring body 51 , thereby preventing the spring 53 from bending and supporting the sliding seat 54 .
